Precision Lead Screws Technical Information Precision lead screws ov-precision_lead_screws_technical_info - Updated - 18-09-2017 Precision Lead Screws from Automotion Components Precision lead screws The high lead thread form maximises linear motion and minimises shaft rotation. The close tolerance, free running nuts are individually matched to their lead screws and are ideal for miniature applications requiring rotary to linear, or linear to rotary actuation. Anti-backlash nuts For applications requiring precision positioning there is now a newly patented Anti-backlash nut. This device, consisting of only three components, utilises the constant force of a compression spring to push two halves apart. This action eliminates any play (backlash) which exists between the internal thread of the nut and the external screw thread. To ensure accuracy and repeatability the nut can be fine tuned through the use of many available spring constants, to meet any preload design requirements. Lead screw specification Lead error Repeatability Straightness Backlash Temperature range Design considerations High precision lead screw ±0,2mm/300mm 0,01mm 0,03mm/100mm 0,08mm (zero when using anti-backlash nut) -30 C to +90 C Critical speed The critical speed of a lead screw is the maximum speed (rpm) before the screw will become dynamically unstable. This results when the forced frequency of the rotating screw corresponds to its natural frequency. Its value is dependent on the length of the screw, the diameter of the thread, and the support configuration. The critical speed value is governed by the following equation. Critical screw speed (RPM) = K x C x 10 6 x (d/l 2 ) Where; K = End support factor 0,36 one end fixed, other free 1,00 simple supports both ends 1,47 one end fixed, one simple 2,23 both ends fixed C = factor 4,5 for Stainless Steel screws 1,6 for Aluminium screws d = Root diameter of the screws L = Length between bearing supports a website from Automotion Components
Technical Information Precision lead screws Precision Lead Screws Load In order to properly incorporate a lead screw into a design, load requirements must be taken into account. These numbers are based on the shear of the nuts and does not take shaft buckling into account. Wherever possible, nuts should be positioned so as to be put in tension, pulling the load. This eliminates the need for buckling considerations. Listed below are some helpful formulae to assist in proper lead screw selection. Where; K = End support factor 0,25 one end fixed, other free (figure 1) 1,00 simple supports both ends (figure 2) 2,00 one end fixed, one simple (figure 3) 4,00 both ends fixed (figure 4) Torque to move a load (T) = F x L/2 x x E Where; F = Load L = Lead E = Efficiency (see product pages) End fixing configurations Critical load (N) = K x C x 10 6 x ( /D 2 ) Figure 1 Figure 3 Double bearing, one end only Double bearing one end, single bearing other end Figure 2 Figure 4 Single bearing both ends C = factor 13,4 for Stainless Steel screws 4,8 for Aluminium screws d = Root diameter of the screws D = Length between bearing supports Double bearing both ends Precision Lead Screws from Automotion Components ov-precision_lead_screws_technical_info_2 - Updated - 18-09-2017 a website from Automotion Components
Precision Miniature Lead Screws Overview Precision Lead Screws Select the relevant size lead screw diameter and load required. These are precision, high helix lead screws from stainless steel (304 grade) We can cut length to suit and/or machine the ends to your requirements They have an accumulative lead error of ±0.20/300mm (C10 grade) The actual clearance depends on the nut selected L1350 standard flanged nut or L1351 antibacklash nut Nuts are very smooth running with little friction. They are made from plastic resin (PPS). The anti-backlash nuts are longer than the standard length nuts as they incorporate a spring pushing the two halves of the unit apart.
